Termination
Daikin McQuay recommends using a twisted shielded pair of
at least 22AWG for the power wire connections. The shield
should be earth grounded only at the power source. Larger
gauge wire may be required for long runs.
CAUTION
Combination of power wiring (R, 5, DH) and analog (1, 2, 3, 4,
and 6 to ground) wiring in a common cable may cause signal
interference and must be avoided.

All wiring must comply with the National Electric Code
(NEC) and local codes. Do NOT run any of this device's wir-
ing in the same conduit as other AC power wiring. Tests show
that fluctuating and inaccurate signal levels are possible when
AC power wiring is present in the same conduit as the signal
lines. If you are experiencing any of these difficulties, please
contact your Daikin McQuay representative
